Understanding CVV and Real Card Numbers
When it comes to online transactions, the terms CVV and real card numbers are often used interchangeably, but they refer to different aspects of a credit card transaction. In this comparison review, we delve into the key differences between CVV and real card numbers.
What is a CVV?
A CVV, or Card Verification Value, is a three or four-digit number printed on the back of your credit card. It is used by merchants to verify that the card is in the possession of the cardholder during card-present transactions. While it is a security feature, it is not used for authentication purposes.
Real Card Numbers
Real card numbers, on the other hand, are the full 16-digit number printed on the front of your credit card. These numbers are used to identify the cardholder and are necessary for all transactions, whether online or in-store.
